After the firmware has been loaded and stored, which takes approximately 8 seconds

to complete, the unit performs a power reset.

Using TFTP: Command Line Interface

To download new firmware from a computer:

1. Enter the following from a TFTP command line interface:

tftp –i <ip address> put <local filename> <destination file name>

The following examples demonstrate the TFTP command sequence to download

the .rom file and the .cob file:

tftp –i 192.168.1.111 put UDS2100_6102.rom U4

tftp –i 192.168.1.111 put UDS2100_webm_1403.cob WEB1

Recovering the Firmware Using the Serial Port and DeviceInstaller

If for some reason the firmware is damaged, you can recover the firmware file by

using DeviceInstaller to download the *.ROM file over the serial port.

To recover firmware:

1. Connect the COM interface of your PC to serial port 1 of the unit.

2. Start DeviceInstaller. If your PC has more than one network adapter, a message

displays. Select an adapter and click OK.

3. From the Tools menu, select Advanced/Recover Firmware. The Serial Port

Firmware Upgrade window displays.

4. For Port on PC, enter the COM port on the PC that is connected to the serial

port of the Lantronix unit.

5. For Device Model, be sure the appropriate device (e.g., UDS2100)

displays.
